Two members of the paparazzi crashed into each other while chasing Justin Bieber on Friday (31.08.12).

The 'Boyfriend' singer was in his Fisker Karma, a luxury sports sedan hybrid vehicle, in Los Angeles when a police officer pulled him over after noticing a Nissan driving "aggressively close behind" him, according to gossip websiteTMZ.

As Justin and the driver of the Nissan explained to the policeman that the car was part of his security detail, several paparazzi arrived on the scene where two of them lost control of their cars and crashed into each other.

No one was hurt and no arrests were made.

This isn't Justin's only run in with a paparazzo. He was previously allegedly involved in a physical altercation with a photographer at The Commons mall in Calabasas, California - where he has purchased a $6.5 million mansion - after a paparazzo attempted to take pictures of him and his girlfriend Selena Gomez.

Following the incident, the photographer called the police before he was taken to hospital complaining of chest pains but he was discharged shortly afterwards.

However, witnesses have claimed the paparazzo was blocking Justin's car in as he was trying to leave the mall, and the singer is then said to have got out of the vehicle to ask him to move away but he didn't so a scuffle broke out.
